or operating conditions.

A further object of the invention is the provision of a structure ofthis character all the parts of which are readily accessible from theinside of the locomotive frame without lifting the frame from the axles.

More specifically my invention contemplates a lateral motion devicewhich is constructed to resiliently urge the axle with its driving boxestoward the middle or normal position. I i

Still more specifically I contemplate the provision of a lever mechanismwhich en,- gages some part of the driving box structure and which isspring pressed to resist relative lateral motion between the box and thelocomotive frame.

How the foregoing together with other objects and advantages areobtained will be clear from the following description considered inconnection with the accompanying drawings which illustrate a convenientembodiment of the invention. I

Fig. 1 is a View in elevation of a portion of a locomotive side framewith my. im; proved lateral motion device applied thereto, the viewbeing taken from the inside of the frame and the driving box properbeing omitted for the sake of clarity;

Fig. 2 is a sectional view through-a pedestal jaw of the frame and themechanism of the presentinvention, taken substantially. on the line 22of Fig. 1, a portion of theaxle and box proper being shown inthisfigure; and I Q F i 3 isa sectional view taken through the Frame andthe device as in icated by the line 33 of Fig. 1.

Referring now more particularly to the drawings the side frame isindicated by the reference character 4:, the same being provided withpedestal ,jaws 5 between which the driving box 6 (Fig. 2) is adaptedwhich is journaled in thebox.

to be mounted. A pedestal binder 7 socures the pedestaljaws together andretains the box therebetween."

fA wear 'compensatingwedge 8 maybe provided on the inner face of one ofthe jaws 5, the same generally being provided with an adjusting stem orrod 9 extending downwardly through an aperture in the pedestal binder 7The pedestal jaws (with or without the wedge 8) are preferably embracedby the flanges 10 of pedestal shoes 11, and it shouldbe noted at thispoint that the flanges 10 do not snugly embrace the pedestal jaws, butare spaced to provide the clearance for lateral motion indicated at12(Figs. 2 and 3). The box-6 is pro.- vided with flangeslii which embracethe shoes 11, their flanges 10 and the jaws 5,

and it should alsobe noted that the box is provided on its outer sidewith a surface 14 adapted to receive the lateral thrust from the hub 15of the wheel '16, the latter, of course, being mounted on the axle 17 Oneither or both sides of the box I provide a mechanism which is adaptedto re silientlyresist lateral motion of the box structure and the axlewith respect to the locomotive frame. This mechanism is constructed asfollows: I p

A member or lever, generally indicated by 18, is provided with aspring'pocket or; seat 19 which is preferably arranged to ex-i tendvertically along an. edge of the box. This member has'two arms 20 whichextend from the pocket 19 away from the box and which are mounted on acommon pivot pin 21. Upper and lower brackets orjlugs 22 and 23,respectively, are securedfto the locomotive frame and are provided'fwithaperturedupstanding lugs 24 adapted toreceive and provide a bearing forthe ends of the pin 21, a The bracket 22 may be pro vided with astrengthening'lug 25 protruding therefrom and engaging the under subface of the upper member of the locomotive side frame 4 (Fig. 1). Thebrackets 22 and 23 may be secured .to the frame {in any suitable manneras by bolts 26. i 1

Abracket member'27 is pivoted on the pin 21 between the arms 20 and isconw structed and configured in such a manner that its free end 28overlies the spring pocket 19 of the lever 18. A spring 29, preferarm 18and is adapted to abut agalnst the ably of the leaf type, is positionedto react between the members 18 and '27, its ends 30 being seated in thepocket 19 and its hand 3l'being seated in the endportion 28 of thebracket, 27 v The bracket 27 is tied to the frame by means of bolts 32tapped into the pedestal "between the shoe and boxflanges lO and 13,respectively, to engage the former.and.re-

ceive the lateral thrust; However, it is quite obvious thatthe tongue 3%could be arranged to receive the thrust from a number of different partsof the box structure, as, for example,-the inner face 35 of the boxitself. 3

A bolt or set screw 36 is provided in each pedestal jaw. It serves tospace or'adjust the tongue 34 with respect to the flange 10 r of theshoe 11. Preferably this adjustment is set to provide a very smallclearance, say one-sixteenth of an inch, between the adj a.- centsurfaces ofv thetongue' and' the flange 10(see 37,Fig. 2).

In considering the operation of my invention it must, of course, beborne in mind that both of the boxes for any particular axle adapted forlateral motion will be provided with my improved lateral motionresisting mechanism and that the mechanism on each side is mounted atthe inside of the locomotive side frame .members. Thus, when a trackcurve or some other road condition causes an axle movement inward fromone side the mechanism on that side will come into action and willresist the lateral motion and tend to return'the axle ,to mid ornormalposition' with respect to the frame. If the thrust is inward fromthe other side, of course, the other resisting mechanism oper s- V 'f f.Y 'My invention, therefore, contemplates a lateral motion resistingmechanism which is very positive in operation and one which is easilyassembledor repaired and capable of convenient and'efl'ectiveadjustment.
